The former Girls Aloud star, who is expecting her first child, whipped fans into a frenzy on Tuesday evening (14 January) before clarifying that she was just reflecting on how amazing the response has been to her pregnancy.
Nadine had tweeted: "I am officially with child! Huge high five to all the ladies with & carrying babies! You are amazing!"
But, after a slew of congratulatory comments, she posted: "No haha she has still not arrived! You are as bad as my family & friends every day they think baby time."
The Northern Irish singer told fans that she was simply feeling "blown away with all the kindness & well wishes since announcing I'm having a baby."
She added: "So many companies & help has been offered. I am emotional at this stage as it is. Your kindness really is overwhelming. Thank you all so much. I am forever grateful."
Nadine surprised fans in August by announcing that she and boyfriend Jason Bell are expecting their first child together. Then, on New Year's Eve, she shared the news that it will be a baby girl.
"2013 has been the best year so far!" she tweeted. "Thank you all for your contribution. Sending loads of love, wishing you all the best for 2014!"
It's been rumoured that Nadine and former American football player Jason became engaged over Christmas, although they have yet to confirm the news.
The couple broke off a previous engagement in 2011 before rekindling their romance.
